...A. R. Gabr; D. A. Cameron; R. Andrews; P. W. Mitchell This paper reviews existing specifications, specifically for the application of crushed concrete or recycled concrete aggregate (RCA) as pavement material for unbound subbases and basecourses. While the use of recycled crushed concrete...

... concretes (recycled coarse aggregates), which have different characteristics and properties compared to natural coarse aggregates, could modify the air content and behavior of recycled concretes. In this paper, some fresh and hardened state properties of entrained air recycled concretes were evaluated...

...AA Di Maio; CJ Zega; LP Traversa In the present paper the errors in compressive strength estimation when the ultrasonic method is applied to conventional and recycled concretes are evaluated. Tests were performed on laboratory prototypes made with conventional concretes containing natural coarse...
